Application tiled January 4, 1902. Serial No. 88,417. KNO model.)

To @ZZ whom it may concern:

Be it known that we, AMBIEHL DomNioK, a citizen of Germany, and LOUIS KRERS, a citizen of the United States, and both residents of New York city, county and State of New York, have invented Certain new and useful Improvements in Boats, of which the following is a specification.

This invention relates to a boat adapted to be propelled by hand by means of paddlewheels which are so constructed that the boat may be easily operated and that splashing is prevented.

In the accompanying drawings, Figure lis a plan of our improved boat; Fig. 2, a side View of one of the paddle-wheels, and Fig. 3 a front View of the boat.

The letter A represents the body of a boat adapted to be propelled by hand and of the size and general construction of a row-boat. From the gunwales of the boat Vextendinwardly a pair of plates a, supported upon blocks b. Each of these plates is provided with a pair of tubular bearings d for the shaft c of a crank c", which is adapted to be operated by hand. Collars d, mounted upon the shaft,.hold the same against axial displacement. To the outer end of each shaft ois secured by socket e' the diametrically extending arm or spoke e of a two-blade paddlewheel. This arm has flattened ends e:a and is so bent that such ends are placed at a greater distance from the boat than its center in order to throw the paddles outward without the use `of outriggers. To the flattened ends e2 are secured the paddles f, which are of oblong shape and provided with reinforcing-ribs f.

The body of the paddles is curved, so that the inner forward edge f2 of each front paddle is turned downwardly or that the inner rear edge 4o of each rear paddle is turned upwardly, Fig. 2, to forni scoops that force the Water laterally away from the boat. The result of this construction is that the paddles will cut into the water gradually and will displace it outwardly,

so that the boat may be easily operated and that splashing will be prevented.

In use the operator faces forward and may propel the boat with ease, the water being so without the use of splash boards or boxes.

lVhat we claim isl. In a boat, a pair of crankshafts combined with bent arms mounted thereon and .taken that the boat will remain entirely dry 5o having their ends placed at a greater distance 5 5 AMBIEHL DOMINICK. LOUIS KREBS.
